To all whom it may) concern:

Be it known that I, GUSTAVUS L. STUE B man, a citizen of the UnitedStates, and'a resldent ,of Flushing, in the county of Queens and Stateof New York, have invented c'ertain new. and useful Improvements inDumping-Buckets with Automatic Locking-Bails, of which the following isa specification.

I in Fig. 4.

The body of the bucket is indicated in its entlrety by the numeral 20,and comprises the side walls 21, rear wall 22, inclined front wall 23and bottom 24. A reinforcing band is fastened to the upper edges of thebody of .the bucket. Reinforcing bands 31 are secured to the rear endsof the. side Walls 21, and reinforcing bands 32 are fastened to thelower ends of said side walls 21. To the rear-wall 22. is fastened thebracket 33 for a dumping rope 34. Stationary axles are indicated at 35and which extend through the triangular protecting hoods 36,

the latter being fastened to the upper face of the bottom 24.Semi-cylindrical protecting hoods 38 are fastened to the bottom 24 atthe opposite ends of the protecting hoods 36.- Wheels 40 are *journaledon the axles 35, and are located within the protecting hoods 38. Each oftheaxles 35 has a split pin 41 extending through the ends thereof and atap screw 42 extends through the eye of said split pins and is inthreaded engagement with a reinforcing plate 43 secured to itsaccompanying reinforcing band 32. Angle stop plates 45 are fastened tothe side walls 21 of the body of the bucket. Reinforcing plates 46 arefastened to the inner faces of theside walls 21 of the bucket andtrunnion plates 47 with the trunnions 48 are fastened to the outer facesof the side walls -and locked with .the trunnions 48. As the 21 oppositethe plates 46.

The invention is shown with two bails, one of which I designate acharging bail with its side view shown in Fig. 1 and the other aPatented Oct. 24, 1916.

Application filed January 22, 1916. Serial No. 78,508.

dumping bail shown with its side view in Fig. 3, whllethe front view ofboth bails is shown in Fig. 4. The charging bail comprises a rear platewith the wings 50, 51, 52'

with a similar vertical guide slot 56 and divergent opening 57. Betweenthe rear and front plates'are fastened the vertical legs 63 of thebails. The latter are connected by horizontal members 64. A strap 65extends from the horizontal member 64; with the nose 76 is pivotedbetween said rear and front plates. on the pin 71, and has formedtherewith the lower inclined guide edge 72 and lug 73. A stop block 74and a filling block 75 are located between said rear and front plates.To the vertical legs 63 of the bail are fastened the hinge brackets 80,and in the latter are pivoted the bell cranks with thearms 81 and 82. Astop lug directed to Fig.1 in which the bail is shown.

locked with the bucket. Previous to the locking of the bail 'with thebucket, the latter is filled with its load, which is generally at apoint distant from the charging bail. The bail. is always suspended onthe hook 90. The bucket can be moved to its proper position for hoistingby means of the tracks 95; After the bucket has been located in properposition the bail is lowered in place bail is lowered in place the lowerinclined guide edges 72 of the hooks 70 bear against A hook 7O the saidtrunnions 48 and swing in the diof its trunnion 48.- Then the hooks 7will become locked with the trunnions 48 by gravity, in other words thebail will be automatically locked with the bucket 20. The

operator then raises the bucket by means of the bail and hoisting chain.The bucket can then be placed on a vehicle or other appurtenance and thebail detached therefrom. The latter operation is performed by loweringthe bail until the stop bars 54 and 55 bear upon the angle stop plates45, and then the operating handle 86 is moved in the direction of thearrow B by which the hooks 70 will" become disengaged from the trunnions48. The bucket is now brought to the dumping station and the bail shownin Figs. 3 and 4- is locked with the trunnions 48. Next the bucket israised by means of the hoisting chain 91, the dumping rope 34 maintainedslack until the bucket is to be dumped. To perform the latter operationthe dumping rope 34 is pulled up, which dumps the bucket as shown inFig. 3. The elimination of the wings 52'and; 53 of the bail allows thebucket 20 to take "the position shown in Fig.3, and the Wings 50 withthe stop bars 54 prevent the bucket turning turtle when dumping byreason of the said stop bars contacting with the pair of angle stopplates 45 at the front end of the bucket.

Referring to Fig. 1 the coaction of the stop bars 54, 55 respectivelywith the angle stop plates 45, prevents the bucket from being tipped ordumped, when being raised, in case it'should strike some obiect.

Having fully described my invention what I desire to secure by LettersPatent and claim is:

1. The combinationin a bucket of trun-- nions, an automatic locking anddetachable bail for the bucket to engage said trunnions and hooks withguide edges bearing against the trunnions when the bail is lowered inplace and thereby said hooks swinging out of the path of the trunnionswhen the bail is lowered in place, the said hooks subsequently lookingwith the trunnions by gravity.

2. The combination in a. bucket of trunnions, an automatic locking anddetachable bail for the bucket having a pair of guide slots to engagesaid trunnions, hooks with lower inclined guide edges bearing againstthe trunnions when thebail is lowered in place and thereby swinging saidhoo-ks out. of the path of the trunnions when said bail is' lowered inplace, the said hooks subsequently looking with the trunnions by gravityand means to unlock the hooks from the trunnlons.

3. The combination in a bucket of trunnions extending therefrom, stopplates exbail to contact with the said tending from the bucket, anautomatic looking bail with guide slots for the bucket, stop bars on thebail to contact with the said stop plates, a hook pivoted on each sideof the bail opposite said guide slots and having inclined guide edges,said inclined guide edges bearing against said trunnions 3vl1en the bailis lowered in place, and thereby swinging the said hooks out of the pathof the trunnions when said-bail is lowered in place, the said hookssubsequently locking with the trunnions by gravity, a link with one endpivoted to each hook and means to raise the links and thereby unlock theHooks from the trunnions. 1

'4.- The combination in a bucket of trunnions therefor, stop platesextending from the bucket, an automatic locking bail with guide slotsfor the bucket, stop bars on the stop plates, a hook pivoted on eachside of the bail opposite said guide slots and having inclined guideedges bearing against the trunnions when the bail is lowered in positionand thereby swinging the said hooks out of the path 'of the trunnions\vhenthe bail is lowered in place, the said hooks subsequently lockingwith the trunnions by gravity, a link with one end pivoted to each hook,a pair of hell cranks pivoted to the bail, the other endof each linkpivoted to one of said bell cranks and an operating handle for the saidbell cranks.

5. The combination in a bucket of trunnions extending from the sidesthereof, an automatic locking bail for the said trunnions, means tounlock the bail from the said trunnions, wheels journaled in the bucket,means to dump the bucket and means on the bucket coacting with the bailto prevent tipping saidbucket before being dumped.

6. The combination in a bucket of trunnions therefor, an automaticlocking bail for said bucket, means on the bail to position the same tolock with the trunnions of the bucket, means to unlock the bail fromsaid trunnions and means to connect rope to the bucket.
